Central motivation of our grant proposal is to critically question the generalizability of the static scene-viewing paradigm. The concerns under scrutiny were raised by Tatler and colleagues (2011) in a review article. We are planning to use mobile eye-tracking in a series of experiments to investigate four effects on eye movements: the effect (i) of body posture and position, (ii) of natural orientation towards a static scene, (iii) of movement preparation during scene perception, and (iv) of depth cues. We will analyze eye movement parameters like the distribution of saccade amplitudes, fixation positions, and fixation durations. In addition, we will compute pair correlation functions, a method from spatial statistics to further understand the dynamics of scanpath generation. Finally, the experimental data will be used twofold: to evaluate an existing dynamical model for the generation of scanpaths and to develop a model of oculomotor error during scene viewing. The models are thought to be fundamental for the development of process models for the control of eye movements in natural settings.

我们的拨款提案的核心动机是批判性地质疑静态场景观看范式的普遍性。Tatler及其同事（2011）在一篇综述文章中提出了这些担忧。我们计划在一系列实验中使用移动眼动追踪来研究对眼球运动的四种影响：(i)身体姿势和位置的影响，（ii）朝向静态场景的自然方向的影响，（iii）场景感知过程中的运动准备，以及（iv）深度线索的影响。我们将分析眼球运动参数，如眼跳振幅分布、注视位置和注视持续时间。此外，我们将计算对相关函数，这是一种来自空间统计的方法，以进一步了解扫描路径生成的动态。最后，实验数据将用于两方面：评估现有的扫描路径生成动力学模型，并开发场景观看过程中的动眼肌误差模型。这些模型被认为是自然环境下眼球运动控制过程模型发展的基础。
